[Stereo-electroencephalographic correlates of motor seizures (author's transl)].
It is generally agreed that surface-EEG findings in focal motor seizures are often ambiguous. With the aid of combined surface- and depth recordings (SEEG-exploration), which we perform on drug resistant epileptics in view of surgical intervention, we find a substantially increased correlation between clinical ictal phenomena and the bioelectric seizure discharges or epileptic paroxysms, provided that a systematic exploration of the motor cortex can be done. Three SEEG-explored patients with primary focal motor seizures illustrate this improved correlation with respect to chronotopographical and formal aspects. The presented cases are also of further interest in that one of them was explored in a status epilepticus and one suffered from an epilepsia partialis continua. Besides the epileptic motor phenomena, the presented cases also illustrate specific features of the bioelectric activity of the Rolandic area, especially the changes of Rolandic EEG-activity produced by voluntary movements.
